Method and Device for Detecting Partial Discontinuous Transmission (DTX) Using Soft Bits Correlation

5. The method of claim 3, wherein the grouping step comprises grouping the multiple sub-sequences into sub-sequence groups based on an assumed condition derived from potential DTX scenarios.

6. The method of claim 5, wherein the assumed condition comprises a number of resource blocks (RBs) not being validly used due to occurrence of a partial DTX state.

7. The method of claim 5, wherein the method is applied iteratively starting with a lowest value of the assumed condition.

8. The method of claim 3, wherein the grouping step can be skipped by treating each of the multiple sub-sequences as a sub-sequence group.

9. The method of claim 3, wherein the grouping step comprises grouping the multiple sub-sequences into a predefined number of sub-sequence groups where each of the sub-sequence groups has one or multiple sub-sequences.

10. The method of claim 9, wherein the predefined number of sub-sequence groups is two and the method further comprises grouping N-n sub-sequences into a first sub-sequence group and grouping a remaining n sub-sequences into a second sub-sequence group, where N is a number of the multiple sub-sequences comprising the soft bit sequence and n is determined based on a number of RBs not used due to the occurrence of a DTX state.

12. The method of claim 1, wherein the evaluating step comprises comparing the determined correlation metrics to at least one selected, calculated or predetermined threshold responsive to determining that any of said determined correlation metrics is less than or equal to said at least one selected, calculated or predetermined threshold then determining that a DTX state has occurred.

13. The method of claim 12, wherein processing of the received linear block encoded signal is terminated once it is determined that a DTX state has occurred.

14. The method of claim 12, wherein the at least one selected, calculated or predetermined threshold comprises any of: a single threshold for all sub-sequence groups; different thresholds for different sub-sequence groups; multiple thresholds for one or more of the sub-sequence groups.

15. The method of claim 14, wherein multiple thresholds for one of said sub-sequence groups comprises a respective threshold for each sequence segment of said sub-sequence group.

16. The method of claim 1, wherein the soft bit sequence is obtained after a signal descrambling process.

17. The method of claim 1, wherein the method comprises dividing the soft bit sequence into multiple sub-sequences of a predefined length and, responsive to determining that a length of a last one of the multiple sub-sequences is less than the predefined length then padding said last one of the multiple sub-sequences with zeros or omitting said last one of the multiple sub-sequences.

18. The method of claim 17, wherein the predefined length comprises a linear block encoded signal encoded codeword length.
